OPEN NOTES

NOTES

Project context and technical decisions.

These notes document what each project is trying to solve, the tradeoffs behind the implementation and the parts that are useful beyond a demo. The full public archive is available in the technical notes section.
PickaRoom product

Why room search needs more than a listing grid

PickaRoom is built around the idea that shared housing decisions depend on compatibility, trust and conversation, not only price and location. The public web explains the product while the app handles private flows such as saved rooms, messages and owner tools.

 Backend practice

Keeping service code predictable

My backend work prioritizes explicit validation, clear API contracts and persistence models that can be tested without depending on the interface. The goal is to keep student projects close to production habits: readable boundaries, recoverable errors and simple deployment paths.

 Public deployment

Preparing a small project site for review

A public site needs more than an app link. I keep crawlable notes, clear policies, an accessible sitemap and stable pages so visitors and reviewers can understand what the project contains before entering private product flows.

PROFILE

Learning by building. Improving by shipping.

I'm a Double Degree student in Computer Science and Telematics, with a backend and systems mindset and a clean-code habit.

iviLab is the public home for my projects and learning notes. It is intentionally small, but each page is written to explain the purpose, state and technical context of the work instead of acting only as a link directory.

PickaRoom is the main active product under this domain. The project page describes the public value of the platform, while the application subdomain contains the interactive account, search and messaging experience.
